American soldiers scurry up a hill after setting gas charges at its base. Next, they are seen ready to remotely set off the charges. They do so, pressing the plungers on their detonators, sumultaneously. The charges explode at the base ot the hill and send huge white clouds of gas billowing over the hill. American soldiers on a hillside overlooking a rural area of France, fire a battery of mortars. Next, the shells are seen striking and exploding in the distance, where they create a virtual wall of gas smoke. Other shells explode, raising black smoke in the midst of the gas. In final scene, several soldiers walk cautiously, widely separated from each other, across a field of flowers, toward the retreating gas cloud, against which they are silhouetted
Wounded United States soldiers in France during World War I. The soldiers load and fire gas shells. Smoke rises from the shells along a hillside. Fields in the foreground. Smoke spreads in the surrounding area. A group of soldiers advances on a field and goes towards a forest area.
Munitions manufacture in Germany. A 70 kg steel ingot is heated in furnace. Workers remove it and place it in a 500 ton press. It is then moved to a drawing press reduces its cross section, lengthens it and cuts it into segments. Workers move it to a reheating furnace where many cylindrical pieces are heated until red hot for forging. They are then moved to a drop forge that further shapes them. A woman war production worker wearing a dress is seen operating the controls of the drop forge heavy equipment in the arms factory.
Munitions manufacture in Germany. Women move newly manufactured heavy munitions casings to a table where they are measured. Worker uses drill press to machine hole for fuse in nose of casing. A woman mounts the casing in a lathe using a chain hoist. She turns (machines ) the outer casing. A small amount of smoke rises from the heat generated at the tool bit. Cutting fluid is poured on the tool bit and casing as it is turning in the lathe. A woman brushes particles from a batch of casings as they are being machined. Men and women perform quality control checks on finished casings. Army representatives perform military acceptance checks on finished casings, using gauges.
Munitions manufacture in Germany. Guide rings are formed and fastened into grooves around munitions casing. Casings are stood on their bases in molds. Molten metal is poured into the molds. Casings with molded metal on bases are removed and placed into lathe where guide rings are machined. Metal chips fly off the lathe during this process. The guide rings are further machined with rotary milling machine. A woman grinds casing surfaces in a machine. Casings are given water pressure checks. Water spouts from a defective casing. Munition casings are cleaned and packed.
Women perform final calibration and hand finishing of munitions casings. Army representatives perform inspections. A woman reams final holes for detonators (fuzes) in casing noses. Munitions are measured and passed through final set of acceptance guages, including a barrel gauge. Women stamp dates and other information on the casings with hammers and dies. The Casings are then rolled across a paint printer and moved by conveyor to shipping area.
